Pro&Con: Using Google's Public DNS as 'default' forwarders

Hello Experts,

in a recent answer here on EE an Expert said this:
8.8.8.8 should be considered really more or less a kind of test DNS server.

I have to admit I never gave it much thought and implementing Google's Public DNS as a common practice since a few years, hence I replied:
8.8.8.8 and 8.8.4.4 point to the load balancers of Google's public DNS. Since these are in truth not a SOA for any domain (and never will be by design). I think of them as perfect forwarders since they will only forward themself. They are also pingable and - as most of the things operated by Google - near perfectly reliable. The DNS servers from my ISPs are not nearly as fast and available. See Google's statement

What are your thoughts?
Thanks,
Helge

I must say - thanks kevinhsieh - that dns benchmark app is cool - I just ran it on a few of my clients servers to test dns performance and make sure they are using a fast forwarder - in Australia I found that Telstra seems to have the best performing DNS for non-cached requests - while the dns of the actual ISP wins for cached requests (as you should expect).

Thank you guys for your Input on that, esp. kevinhsieh for the benchmark-tool! Enabled me to find out my best performing DNS.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
